"So Complex" is an interactive and strategic board game about a typical Rio de Janeiro favela, admired for its rich culture and feared because of the violence that assails the community. The game invites players to learn about local structures and think about possible solutions for local problems. Three to six players playfully compete to 'build' the favela, trying to improve its quality of life. A ride on the newly-built and controversial cable car in the community generates different types of typical situations for players to deal with. During the game, different challenges and problems occur in the favela, posing obstacles to its development.​ The game's objective is to involve high school and university students from the favela and from middle- and upper-class neighborhoods, and get them to discuss the potential, problems and solutions applicable to informal settlements.
